refdb: catch additional per-worktree refs
The upstream git.git project currently identifies all references inside
of `refs/bisect/` as well as `HEAD` as per-worktree references. This is
already incorrect and is currently being fixed by an in-flight topic
[1]. The new behavior will be to match all pseudo-references outside of
the `refs/` hierarchy as well as `refs/bisect/`.
Our current behavior is to mark a selection of pseudo-references as
per-worktree, only. This matches more pseudo-references than current
git, but forgets about `refs/bisect/`. Adjust behavior to match the
in-flight topic, that is classify the following references as
per-worktree:
- everything outside of `refs/`
- everything inside of `refs/bisect/`

repository: rename `path_repository` and `path_gitlink`
The `path_repository` variable is actually confusing to think
about, as it is not always clear what the repository actually is.
It may either be the path to the folder containing worktree and
.git directory, the path to .git itself, a worktree or something
entirely different. Actually, the intent of the variable is to
hold the path to the gitdir, which is either the .git directory
or the bare repository.
Rename the variable to `gitdir` to avoid confusion. While at it,
also rename `path_gitlink` to `gitlink` to improve consistency.

refdb: introduce commondir awareness
The refdb_fs_backend is not aware of the git commondir, which
stores common objects like the o bject database and packed/loose
refereensces when worktrees are used.
Make refdb_fs_backend aware of the common directory by
introducing a new commonpath variable that points to the actual
common path of the database and using it instead of the gitdir
for the mentioned objects.

refdb: rename refdb_fs_backend's .path to .gitpath
The variable '.path' of the refdb_fs_backend struct becomes
confusing regarding the introduction of the git commondir. It
does not immediatly become obvious what it should point to.
Fix this problem by renaming the variable to `gitpath`,
clarifying that it acutally points to the `.git` directory of the
repository, in contrast to the commonpath directory, which points
to the directory containing shared objects like references and
the object store.

This includes ignoring an unlinking error. Either someone else removed
it or we leave the file around. In the former case the job is done, and
in the latter case, the ref is still in a valid state.

In order not to undo concurrent modifications to references, we must

refdb_fs: fail if refcache returns NULL pointer

The fail-label of `reflog_parse` explicitly checks the entry
poitner for NULL before freeing it. When we jump to the label the

the allocation fails we immediately return with an error code and
if the loop was not entered we return with a success code,
withouth executing the label's code.
Remove the useless NULL-check to silence Coverity.

git_futils_mkdir_*: make a relative-to-base mkdir
Untangle git_futils_mkdir from git_futils_mkdir_ext - the latter
assumes that we own everything beneath the base, as if it were
being called with a base of the repository or working directory,
and is tailored towards checkout and ensuring that there is no
bogosity beneath the base that must be cleaned up.
This is (at best) slow and (at worst) unsafe in the larger context
of a filesystem where we do not own things and cannot do things like
unlink symlinks that are in our way.

refdb: use the same id for old and new when renaming a reference
When we rename a reference, we want the old and new ids to be the same
one (as we did not change it). The normal code path looks up the old id
from the current value of the brtanch, but by the time we look it up, it
does not exist anymore and thus we write a zero id.
Pass the old id explicitly instead.

Disallow:

2. paths with trailing space
3. paths with trailing colon
4. paths that are 8.3 short names of .git folders ("GIT~1")
5. paths that are reserved path names (COM1, LPT1, etc).
6. paths with reserved DOS characters (colons, asterisks, etc)
These paths would (without \\?\ syntax) be elided to other paths - for
example, ".git." would be written as ".git". As a result, writing these
paths literally (using \\?\ syntax) makes them hard to operate with from
the shell, Windows Explorer or other tools. Disallow these.

Improve GIT_EUSER handling
This adds giterr_user_cancel to return GIT_EUSER and clear any
error message that is sitting around. As a result of using that
in places, we need to be more thorough with capturing errors that
happen inside a callback when used internally. To help with that,
this also adds giterr_capture and giterr_restore so that when we
internally use a foreach-type function that clears errors and
converts them to GIT_EUSER, it is easier to restore not just the
return value, but the actual error message text.
|
|

Remove converting user error to GIT_EUSER
This changes the behavior of callbacks so that the callback error
code is not converted into GIT_EUSER and instead we propagate the
return value through to the caller. Instead of using the
giterr_capture and giterr_restore functions, we now rely on all
functions to pass back the return value from a callback.
To avoid having a return value with no error message, the user
can call the public giterr_set_str or some such function to set
an error message. There is a new helper 'giterr_set_callback'
that functions can invoke after making a callback which ensures
that some error message was set in case the callback did not set
one.
In places where the sign of the callback return value is
meaningful (e.g. positive to skip, negative to abort), only the
negative values are returned back to the caller, obviously, since
the other values allow for continuing the loop.
The hardest parts of this were in the checkout code where positive
return values were overloaded as meaningful values for checkout.
I fixed this by adding an output parameter to many of the internal
checkout functions and removing the overload. This added some
code, but it is probably a better implementation.
There is some funkiness in the network code where user provided
callbacks could be returning a positive or a negative value and
we want to rely on that to cancel the loop. There are still a
couple places where an user error might get turned into GIT_EUSER
there, I think, though none exercised by the tests.

reflog: integrate into the ref writing
Whenever a reference is created or updated, we need to write to the

leave that to the ref frontend, but integrate it into the backend.
This also eliminates the race between ref update and writing to the
reflog, as we protect the reflog with the ref lock.
As an additional benefit, this reflog append on the backend happens by
appending to the file instead of parsing and rewriting it.

Initial iconv hookup for precomposed unicode
This hooks up git_path_direach and git_path_dirload so that they
will take a flag indicating if directory entry names should be
tested and converted from decomposed unicode to precomposed form.
This code will only come into play on the Apple platform and even
then, only when certain types of filesystems are used.
This involved adding a flag to these functions which involved
changing a lot of places in the code.
This was an opportunity to do a bit of code cleanup here and there,
for example, getting rid of the git_futils_cleanupdir_r function in
favor of a simple flag to git_futils_rmdir_r to not remove the top
level entry. That ended up adding depth tracking during rmdir_r
which led to a safety check for infinite directory recursion. Yay.
This hasn't actually been tested on the Mac filesystems where the
issue occurs. I still need to get test environment for that.

Rewrite refdb_fs using git_sortedcache object
This adds thread safety to the refdb_fs by using the new
git_sortedcache object and also by relaxing the handling of some
filesystem errors where the fs may be changed out from under us.
This also adds some new threading tests that hammer on the refdb.

Don't try to pack symbolic refs
If there were symbolic refs among the loose refs then the code
to create packed-refs would fail trying to parse the OID out of
them (where Git just skips trying to pack them). This fixes it.

Use pool for loose refdb string allocations
Instead of using lots of strdup calls, this adds a memory pool to
the loose refs iteration code and uses it for keeping track of the
loose refs array. Memory usage could probably be reduced even
further by eliminating the vector and just scanning by adding the
strlen of each ref, but that would be a more intrusive changes.
This also updates the error handling to be more thorough about
checking for failed allocations, etc.

git_reference_next_name must match git_reference_next
The git_reference_next API silently skips invalid references when
scanning the loose refs. The git_reference_next_name API should
skip the same ones even though it isn't creating the reference
object.
This adds a test with a an invalid loose reference and makes sure
that both APIs skip the same entries and generate the same results.

Reorganize diff and add basic diff driver
This is a significant reorganization of the diff code to break it
into a set of more clearly distinct files and to document the new
organization. Hopefully this will make the diff code easier to
understand and to extend.
This adds a new `git_diff_driver` object that looks of diff driver
information from the attributes and the config so that things like
function content in diff headers can be provided. The full driver
spec is not implemented in the commit - this is focused on the
reorganization of the code and putting the driver hooks in place.
This also removes a few #includes from src/repository.h that were
overbroad, but as a result required extra #includes in a variety
of places since including src/repository.h no longer results in
pulling in the whole world.

Make iterators use GIT_ITEROVER & smart advance
1. internal iterators now return GIT_ITEROVER when you go past the
last item in the iteration.
2. git_iterator_advance will "advance" to the first item in the
iteration if it is called immediately after creating the
iterator, which allows a simpler idiom for basic iteration.
3. if git_iterator_advance encounters an error reading data (e.g.
a missing tree or an unreadable file), it returns the error
but also attempts to advance past the invalid data to prevent
an infinite loop.
Updated all tests and internal usage of iterators to account for
these new behaviors.

Fix refdb iteration early termination bug
There was a problem found in the Rugged test suite where the
refdb_fs_backend__next function could exit too early in some
very specific hashing patterns for packed refs. This ports
the Rugged test to libgit2 and then fixes the bug.

refs: remove the OID/SYMBOLIC filtering
Nobody should ever be using anything other than ALL at this level, so
remove the option altogether.
As part of this, git_reference_foreach_glob is now implemented in the
frontend using an iterator. Backends will later regain the ability of
doing the glob filtering in the backend.
